Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a cabinet heater, the combination of a hot air casing comprising a front wall having a central opening at the upper end thereof, a top having a delivery opening at each side thereof provided with outwardly inclined louvers and a central delivery opening between said side delivery openings provided'with transversely disposed pivoted louvers adapted to close the central opening and when in open position to incline forwardly, a bar connecting said pivoted louvers, a closure for said front opening pivoted at its lower edge, and a link connecting said front opening closure with said pivoted louvers whereby the pivoted louvers may be opened and closed by the opening and closing of said front opening closure, said front opening closure constituting a counterbalance member for the pivoted louvers when the closure members and louvers are in open position.

2. In a cabinet heater, the combination of a hot air casing comprising a front wall having a central opening at the upper end thereof, a top having a delivery opening at each side thereof.

provided with outwardly inclined louvers and a central delivery opening between said side delivery openings provided with transversely disposed pivoted operatively' connected louvers adapted to close the central opening and when in open position to incline forwardly, a closure for said front opening, and connections for said front opening closure with said pivoted louvers whereby the pivoted louvers, may be opened and closed by the opening and closing of said front opening closure.

3. In a cabinet heater, the combination of a casing comprising a wall having an opening adjacent the upper end thereof and a top provided with adjustablejouvers, means in the casing for directing heated air in said casing toward said wall from the opposite side of the casing and upwards to and through said opening when the latter is open, a closure for the opening, and connections between said closure and louvers to permit simultaneous adjustment of said closure and louvers.
